One of the most amazing things about the area around Iguazu Falls is the incredible profusion of butterflies. In the early morning, you can find them setting on rails and plants, an abundance of different types. As the sun begins to dry their wings, they start to fly about, at times you can see many dozens in one view. Many types come together in assemblies, literally hundred of individuals in close proximity.
